output_all: fix off-by-one error in audio_output_all_check()

When there are chunks which are not yet finished, audio_output_all_check() returned the size of its music pipe minus one. I can't remember exactly why I subtracted 1 from the return value, it must have had something to do with a former meaning of this function. Now it induces assertion failures.
